DOFFER-COMB FOR CARDING-MACHINE S'.

SPECIFIGATIONforming part of Letters Patent No. 548,788, dated October29, 1895. Application filed November 26,1894- Serial No. 529,921. (Nomodel.)

To all whom it may concern.-

Be it known that 1, CHARLES G. REILLY, of the city of Troy, county ofRensselaer, and State of New York, have invented a new and usefulImprovement in Dofier Combs for Oarding-Machines, of which the followingis a specification.

My invention relates to dofEer-combs, and more particularly to a methodof connecting the comb to the rock-shaft, the object and purpose of myinvention being to better adapt this class of apparatus to the uses forwhich it is designed, to connect the dofier-comb'with the rock-shaft ina way to render the attachment secure and permanent, and to cheapen thecost of construction.

Accompanying this specification to form a part of it there are threeplates of drawings containing nine figures illustrating my invention,with the same designation of partsby letter reference used in all ofthem.

Of the illustrations, Figure 1 is a top view of a part of acarding-cylinder, a doffer-comb in transverse section. Fig. 5 is across-section taken through the housing, the driving-shaft eccentric,the eccentric-sleeve, the slide-bar on the latter, and the head of therock-shaft in which the bar operates to reciprocatingly Fig. 6 is asection rotate the rock shaft.

taken on the line m m of Fig. 5. Fig. 7 is a section taken on the line m00 of Fig. 5. Fig. 8 is a section taken on the line 00 m of Fig. 1, 'andFig. 9 is a section taken on the line 00 m otFig.1. r l

The several parts of the apparatus thus illustrated are designated byletter reference Fig. 3 shows and the function of the parts is describedas follows:

The letter F designates parts of the carding-machine frame, and C thecarding-cylinder, having card-clothing c on its cylindrical face.

The letter R designates the rock-shaft by which thedofEer-comb isoperated to vibrate.

This rock-shaft has one of its end bearings at passes diametricallythrough the head, andthis latter is caused to be rotated reciprocatinglyby means of a cylindrical-form slidebar, J, which is formed integrallywith and offset from a sleeve G, arranged on the eccentric-head Pof thedriving-shaft S so that as the'latter is actuated by the pulley M, itmoves the sleeve G eccentrically and causes the bar J to slide back andforth in the passage'D of the head I, and from the constantly changingcenter of the eccentric on the driving-s'haft head the head I of therock-shaft R and the latter are caused to reciprocatingly rotate abouthalf a turn, and the doEer-comb connected with said rock-shaft isoperated to pick into and then move out from the material on thecarding-cylinder carried along by its card-clothin g.

The letter O designates the doffer-comb, which is made of sheet metal,having teeth t cut in its lower edge e, as shown in section at Fig. 8.This dofier-comb is made with a vertical part 0 and a horizontal part 0thus formed by bending downwardly at right angles the teeth part fromthe horizontal part. The latter part of the dot'fer-comb is made with araised rib on its upper surface, as indicated at B which is continuedthroughout its length, and has upon its under surface" the groove 9.

The letter K designates arms which at their outer ends make adjustableconnection with the rock-shaft, which will be described hereinafter.These arms K are on their inner ends made with a fiat surfacef, which isplaced beneath and so as to be in contact with the horizontal comb part0 and the Hat surfacef is made with a rib k adapted to interlock withinthe groove 9 on the under sideof the comb part 0 The letters WVdesignate clamp-plates adapted to be passed on over the top of thehorizontal comb part, and they are each made with a cross-groove g forinterlocking with the rib R made on the top of the horizontal comb part,and each of them is let into each of the arms K at h, which thereat areboth semicircular in form. 1

The letter N designates a nut which is threaded onto the semicircularshank n of each of the clamp-plates and the half-round part of each ofthe arms K, so that when the said nut is screwed onto the shank of theclamp and the adjacent arm K, as shown at Fig. 8, the comb is securelyconnected to the arm. The outer end of each of the arms K passes throughthe four-part tube-fitting W of the tube-form rock-shaft, as shown atFigs. 8 and 9, and are each made adjustable thereon by means of a barat, made with an eye 6 at its lower end for the insertion of each of thearms K where passing through the shaft, and which bar at its upper endin each instance is provided with a threaded nut N, from which the barpasses through a bushing T screwed into a nipple v, by which the bar maybe raised or depressed to raise or depress the arm K.

The letter o designates a washer placed between the nut N and thebushing T The rock-shaft R is preferably made of gaspipe, and theconnections between it and the arms K are in each instance of their useproduced by means of four-way. gas-pipe fittings having a threaded topopening containing a bushing made with a central passage for the bar mwhich hooks onto one of the arms K in each instance, and which bar isprovided with an adjusting nut and washer.

' While 1 have shown the rock-shaft as broken apart for convenience ofillustration and with but one of the arms K applied to each part of therock-shaft, there may be more of them used and applied in the samemanner.

The eccentric-sleeve G is made with an interior surface 9 that tapersinwardly as extended outwardly, and the eccentric-head I of thedriving-shaft S is made to exteriorly taper to correspond with theinterior surface of the eccentric-sleeve G, as shown at Fig. 6, and theletter O designates a collar arranged on the driving-shaft S to abutagainst its bearing b and this collar is provided with a set-screw 0 bythe engagement of which with the collar and shaft S the taperingsurfaces of the eccentric sleeve and head are kept in contact, and bywhich, should they wear away by use, they may be drawn to contact and sosecured by this set-screw 0 The letter U designates the cover of thehousing H, and the latter is, when the machine is running, filled withlubricant.

The letter B designates the bed in which the housing rests on the frameF, and the letters Z designate lugs that are upcast from the bed at eachside of the housing, and the letters T designate set-screws threadedinto each of these lugs and adapted to bear upon the projection i oneach side of the housing, whereby the latter, as adjusted laterally onthe bed B, may be secured in position by these set-screws, as shown atFigs. 2, 3, and 5.

The letter M designates the driving-pulley, which is arranged on theshaft S Y As thus made and arranged, a doffer-comb can be operated tovibrate with great rapidity and with a steady and noiseless motion, andfrom the manner in which its parts, as well as those actuating it, areconstructed, they may be made cheaply without impairing theirefficiency.

I am aware that doffer-comb rock-shafts have been actuated by means of adrivingshaft having a head eccentrically arranged thereon and providedwith asleeve having a slide bar projected therefrom which was adapted tomove in a slldeway formed on the head of the rock-shaft. My improvementon this older feature of mechanism relates to the tapering surfaces ofthe sleeve and eccentric head, by which, as the bearing parts becomeworn, by means of a nut they may be brought to contact and held by thelatter.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination in a doffer comb having a rib formed in the uppersurface of its horizontal part, and a groove in its lower surface, of anarm made with a flat surface having a cross-rib adapted to enter thegroove in the lower surface of the horizontal part, a clamping platemade with a cross-groove adapted to receive the rib on the upper surfaceof the horizontal part, and a nut threaded onto, so as to embrace saidarm and clamp, substan tially in the manner as and for the purposes setforth.

2. The combination with the doffer-comb 0,-

made with the horizontal part 0 having the rib B on its upper surfaceand the groove 9 on its lower surface, and the down-cast comb-part 0made with the teeth t; of the arms K, each made with the flat face f,having the cross-rib on its upper surface and arranged beneath thehorizontal comb-part C and each of said arms provided with a clamp-plateW, that is let into each of the arms, and provided with a nut that isthreaded onto, so as to embrace the shank of the clamp plate and armwhere under-lapping the latter, substantially in the manner as and forthe purposes set forth.

3. The combination with the rock-shaft R made in a tube-form and havingthe four-way fittings W arranged thereon; of the arms K, each arrangedto be passed horizontally through one of said fittings at right anglesto said shaft and therein secured by means of a bar having an eye on itslower end to receive the arm, and which bar where passed upwardlythrough said fittings being provided with a nut threaded thereon,substantially in [o the manner as and for the purposes set forth.
